[0040] Please refer to Figure 1 and Figure 12 , the present utility model provides a vehicle charger for buffering and retracting a wire, including:

[0041] A damper 1, the damper 1 includes a rotating member 11 and a decelerating member 12. The rotating member 11 is provided with an external tooth 111 and an internal tooth 112. The external tooth 111 is provided on the outer wall of the rotating member 11, and the internal tooth 112 is provided on the inner wall of the rotating member 11. The decelerating member 12 is provided in the rotating member 11, and the decelerating member 12 is meshed and connected with the internal tooth 112;

[0042] The telescopic charging cable 2, the telescopic charging cable 2 includes a conductive component 21, a wire winding component 22 and a wire 23. The conductive component 21 is fixedly connected to the wire winding component 22. One end of the wire 23 is fixedly connected to the conductive component 21. The wire winding component 22 drives the wire 23 to perform telescopic movement. The rotating member 11 is meshed and connected to the wire winding component 22;

[0043] The circuit component 3, the circuit component 3 includes a plurality of pins 31 and a circuit board 32. The pins 31 are fixed on the circuit board 32. The circuit board 32 is electrically connected to the conductive component 21.

[0044] The circuit component 3 is responsible for conducting the vehicle power supply to the telescopic charging cable 2. Specifically, it is connected to the internal circuit of the vehicle through the pins 31. The pins 31 then conduct the circuit board 32. The conductive component 21 of the telescopic charging cable 2 is electrically connected to the circuit board 32. Specifically, the conductive component 21 is provided with a power connection part 211, and the circuit board 32 is provided with a conductive position 321. The power connection part 211 is inserted into the conductive position 321; the conductive component 21 conducts the wire 23. The wire winding component 22 is responsible for providing an elastic contraction force for the wire 23 or automatically winding up the wire 23 and controlling the stretching length of the wire 23. When the wire 23 is retracted, the wire winding component 22 will engage and drive the rotating member 11 of the damper 1. The speed reducer 12 is meshed and connected to the internal teeth 112. The rotation speed of the rotating member 11 is slowed down through the speed reducer 12, and the rotation speed of the wire winding component 22 is further slowed down, so as to control the retraction speed of the wire 23, and the wire 23 can be slowly wound up.

[0045] It should be noted that: the more detailed structure of the conductive component 21 is described in a prior application of a conductive component 21, a vehicle charger and a travel power bank with the patent number 202420076372.1, and will not be elaborated in this application.

[0046] Specifically, the structure in which the rotating member 11 is meshed and connected to the wire winding component 22 is:

[0047] The wire winding component 22 includes a positioning device 221. The positioning device 221 includes a first turntable 2211. The first turntable 2211 is provided with a gear 22111. The gear 22111 is meshed and connected to the external teeth 111. When the wire 23 is retracted, the first turntable 2211 will rotate, and drive the gear 22111 on the first turntable 2211 to rotate, so as to drive the rotating member 11 of the damper 1 to rotate; when the rotation speed of the rotating member 11 decreases, it will also affect the rotation speed of the first turntable 2211.

[0048] It should be noted that the more detailed structure of the wire winding component 22 is described in a prior application of a telescopic data cable and a power socket with the patent number 202320866543.6, and will not be elaborated in this application.

[0049] Further, the structure of the damper 1 will be described:

[0050] A convex shaft 113 is provided inside the rotating member 11, and a groove 121 is provided inside the decelerating member 12. The groove 121 is sleeved on the convex shaft 113, so that the decelerating member 12 can rotate inside the rotating member 11.

[0051] The decelerating member 12 includes an upper section 122, a lower section 123, and convex teeth 124. The convex teeth 124 are located between the upper section 122 and the lower section 123, and the convex teeth 124 are meshed with the internal teeth 112. Therefore, the decelerating member 12 specifically uses the frictional force generated by the meshing transmission of the convex teeth 124 on it and the internal teeth 112 of the rotating member 11 to reduce the rotation speed of the rotating member 11. It should be noted that the design of the convex teeth 124 is a preferred implementation method. When there are no convex teeth 124, the internal teeth 112 directly rub against the outer wall of the decelerating member 12, and the rotation speed of the rotating member 11 can also be reduced.

[0052] The damper 1 further includes a cover 13. The cover 13 is sleeved on the outer wall of the upper section 122, and the decelerating member 12 is stabilized inside the rotating member 11 by designing the cover 13.

[0053] A rubber ring 14 is provided between the cover 13 and the decelerating member 12, and the sealing performance of the cover 13 is enhanced by providing the rubber ring 14.

[0054] After the existing telescopic data cable product recovers the wire 23, its charging interface protrudes outside the housing and the charging interface cannot be stored. Therefore, it is necessary to design the charging interface to be storable, and the specific structure is as follows:

[0055] A vehicle-mounted charger for buffering and storing a wire of the present utility model further includes a housing assembly 4. The damper 1, the conductive assembly 21, the wire winding assembly 22, the wire 23, and the circuit board 32 are all arranged inside the housing assembly 4. The other end of the wire 23 passes out of the housing assembly 4. The housing assembly 4 includes a magnetic attracting object 41. The wire 23 is provided with an adsorption sleeve 231. The adsorption sleeve 231 can be adsorbed and attached to the surface of the magnetic attracting object 41, and the adsorption sleeve 231 can be made of iron material.

[0056] The housing assembly 4 further includes an outlet 43. A snap ring 232 is provided on the wire 23. The snap ring 232 is clamped at the outlet 43. The design of the snap ring 232 limits the length of the wire 23 exposed outside the housing assembly 4. Referring to Figure 12 , the exposed part of the wire 23 is bent, and the adsorption sleeve 231 is attracted and attached to the magnetic attracting object 41, so that the charging interface of the wire 23 is stored in the housing assembly 4.

[0057] Further, how the damper 1 is connected to the telescopic charging cable 2 is specifically as follows:

[0058] A connection hole 125 is provided on the decelerating member 12. The housing assembly 4 further includes an inner housing 42. The inner housing 42 is provided with a connection post 421. The connection post 421 is disposed within the connection hole 125. Refer to Figure 1 , the telescopic charging cable 2 and the damper 1 are disposed within the inner housing 42. The inner housing 42 is divided into upper and lower halves. When the two halves are fixedly connected, the rotating member 11 is meshed and connected to the winding assembly 22.

[0059] The above-described embodiments merely represent one implementation manner of the present utility model, and the description thereof is relatively specific and detailed. However, it should not be construed as a limitation to the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
